Empirically extending 1D Child-Langmuir theory to a finite temperature beam
Jesse M. Snelling, Gregory R. Werner, John R. Cary
Numerical solutions to the 1D steady-state Vlasov-Poisson system are used to develop a straightforward empirical formula for the electric current density transmitted through a vacu…
Attosecond-Angstrom free-electron-laser towards the cold beam limit
A. F. Habib, G. G. Manahan, P. Scherkl +13
Electron beam quality is paramount for X-ray pulse production in free-electron-lasers (FELs). State-of-the-art linear accelerators (linacs) can deliver multi-GeV electron beams wit…
Single Gaussian Process Method for Arbitrary Tokamak Regimes with a Statistical Analysis
Jarrod Leddy, Sandeep Madireddy, Eric Howell +1
Gaussian Process Regression (GPR) is a Bayesian method for inferring profiles based on input data. The technique is increasing in popularity in the fusion community due to its many…
Chromatic Dynamics of an Electron Beam in a Plasma Based Accelerator
R. Ariniello, C. E. Doss, V. Lee +3
We present a theoretical investigation of the chromatic dynamics of the witness beam within a plasma based accelerator. We derive the single particle motion of an electron in an io…
Growing Neoclassical Tearing Modes Seeded via Transient-Induced-Multimode Interactions
E. C. Howell, J. R. King, J. D. Callen +3
Nonlinear extended MHD simulations demonstrating seeding of neoclassical tearing modes (NTMs) via MHD-transient-induced multimode interactions are presented. Simulations of NTMs ar…
Time-discretization of a plasma-neutral MHD model with a semi-implicit leapfrog algorithm
Sina Taheri, Jacob R. King, Uri Shumlak
The semi-implicit leapfrog time-discretization is a workhorse algorithm for initial-value MHD codes to bridge between vastly separated time scales. Inclusion of atomic interactions…
